Loveletter for u #1

15-10-2017

Sådan noget her er altid lidt farligt. For man ved ikke om google forevigt blacklister en. Men dengang i år 2000 blev der udsendt en virus kaldet I LOVE YOU eller loveletter eller sågar lovebug. Dette er koden til denne.

Programmet, eller scriptet, er skrevet i VBscript som er et scriptsprog beregnet til at køre små stykker kode, feks. ved opstart af computeren.

Scriptet har endelsen .txt.vbs - på windows skjules den sidste del normalt, derfor kommer scriptet til at se ud som en .txt fil. Hvis man kører det på en windowsmaskine, en sikkert ikke al for ny en, knalder det alle ens dokumenter, .mp3, .doc og den slags, det erstatter dem med en kopi af scriptet. Derefter sender det sig selv til alle venner i ens indbakke.

ILOVEYOU nåede at inficere 45 millioner computere og gjorde skade for mere end fem milliarder $.

På google.groups kan man se tråde der omhandler virussen fra de dage den gik amok: Google.Groups. En af de øverste er en analyse af virussen.
